The Windsor Locks teenager diagnosed with Hodgkin's lymphoma who battled the state over chemotherapy treatment is in remission, according to sources familiar with the case.

Department of Children and Families Commissioner Joette Katz said in a statement released Sunday:

"We are very pleased with Cassandra's progress toward a complete recovery. We understand how difficult this has been for Cassandra and her family, but we have had full confidence throughout that the medical professionals involved in her treatment would be successful in saving her life."

On Jan. 8, the state Supreme Court let stand a Superior Court order that gave DCF temporary custody of 17-year-old Cassandra C., as she is known in court papers, who had run away after receiving two chemotherapy treatments. Court-ordered treatment began in late November, and was set to run for six months.

Cassandra will turn 18 in September, and at that point could make medical choices on her own as an adult. At issue in the court battle was whether a minor could be mature enough to make those decisions, and whether Cassandra fit that category.

Doctors testified at Superior Court hearings in November and December – and DCF's lawyer repeated before the Supreme Court – that without chemotherapy, Cassandra would die. With treatment, according to testimony, she has an 80 percent to 85 percent chance of survival and full recovery.
